Field solver experts: I have some generic questions. Consider the well-known finite element method(FEM) solver and assume full-wave solution and almost perfect boundary, unless mentioned otherwise. 1) Are there any benchmarks on the speed of these solvers compared to other kinds of solvers in time-domain or frequency-domain? 2) If a raw, non-optimized solver does it in T time, what is the likely max. speed improvement using conceptual or computational optimization? An educated guess will help for a start. 3) Suppose a solver is designed to solve for only three E(or H)components, instead of all six field components. What is the likely max. speed improvement? Again, an educated guess will help for a start. 4) Would you consider the solver in 3) a full-wave solver? If yes, under what conditions? If no, please give reasons. 5) If you were to design the solver in 3), what kind of conceptual pitfalls, if any, would you look for and try to avoid?
